CT1/PRI interface view
Parameter
set-number: The number of the channel-set formed by bundling the timeslots of
the interface, which is in the range of 0 to 23.
range: The number of the timeslots that are bundled, which is in the range of 1 to
24. When specifying the timeslots to be bundled, you can specify a single timeslot
by specifying a number, a range of timeslots by specifying a range between
number1-number2, or several discrete timeslots by specifying number1,
number2-number3.
speed { 56k | 64k }: The speed of the timeslot bundle, which is in Kbps. If 56k is
selected, the timeslots will be bundled into N x 56 Kbps bundles, and if 64k is
selected, the timeslots will be bundled into N x 64 Kbps bundles. By default, the
system uses 64k.
Description
Using the channel-set command, you can bundle some timeslots of a CT1/PRI
interface into a channel-set. Using the undo channel-set command, you can
remove the specified channel-set.
By default, no timeslots are bundled into channel-sets.
A CT1/PRI interface is physically divided into 24 timeslots numbered from 1
through 24. In actual applications, all the timeslots can be bundled into multiple
channel-sets and the system will automatically create a serial interface for each
set. This serial interface has the same logic features of synchronous serial interface.
The serial interface is numbered in the form of serial interface-number:set-number.
Where, interface-number starts from the maximum serial interface number plus 1,
and set-number is the number of the channel-set.
Only one timeslot bundling mode can be supported on one CT1/PRI interface
during a time period. In other words, this command cannot be used together with
the pri-set command.
For a related command, see pri-set.
Example
Bundle the timeslots 1, 2, 5, 10-15and 18 of the CE1/PRI interface into
channel-set 0.
